LCDproc Server
Cli:o Scr:0

I would say that there is some misconfiguration in a file that is not routing the information to the LCD.

In order to see if this was a problem with wrong wiring, I installed RaspBMC and it worked beatifully.

Could any of you who have it working put the image in a Dropbox so I can download it ? I would have only to reconfigure my Wifi and DLNA.

Thanks for your help.

I found the problem, if you just select the code on the blog and paste it in an textfile the indentation will be messed up. This is caused by the java-script that embeds source-code on blogger-pages (I autogenerated that part at another webpage where I just pasted my code). I have manually fixed the code on the page, i.e. removed one white-space in the beginning of each row.
Try to copy the code from the blog again and it will hopefully work.
Don't forget to put the showSongInfo.py file with the code in /home/pi/Adafruit-Raspberry-Pi-Python-Code/Adafruit_CharLCDPlate/ (or wherever you installed the Adafruit libs), otherwise the import of Adafruit_CharLCDPlate will not work.
Thank you for pointing out the problem.

Ok. That´s right now. However, i can not change the radio station with buttons. This is message:
"Traceback (most recent call last):
File "showSongInfo.py", line 65, in
time = statusLines[1].split(' ',1)[1].strip()
IndexError: list index out of range"
I have 4 radio station on Raspyfi Playlist.
Thanks for your information and efforts

Hi,
I have the same problem when I try to play radio stations that mpd cannot connect to. When I play "working" stations everything looks fine. I didn't try the code on radio stations earlier but now I realise that I must add some error checking in the code to handle this error.
The workaround for this problem should be to only add working stations to the playlist. If this doesn't help please tell me which stations that hangs the python script and I will try to find the problem.

I will update the code on the blog as soon as possible to handle stations that the mpd cannot connect to.

If anyone knows how to display the radio station name on the top line of the display when streaming please share. At present the top line displays "" with the bottom line displaying the artist and song title. Thank you, Chris

I followed your very helpful guide Andy and managed to get it working. Thank you for this.Did have one very strange thing happening though. I added the sudo mpdlcd --no-syslog & line to the rc.local file and saved it and checked it was there. But on rebooting the line disappears from rc.local every time and the LCD shows an error! Only way to fix this is to SSH into the Pi and then run sudo mpdlcd --no-syslog & from the command line. It then works fine - any idea how to stop rc.local removing the line at reboot? Also it took me a while to realize from your guide that sudo mpdlcd –no-syslog & really should be sudo mpdlcd --no-syslog & (ie need double dash -- and not a single – ) shown in your guide.

I had the same problem. You have to be SU before edit RC.LOCAL

Many thanks for your comment Leopoldo. I logged in as SU and tried this, but on reboot the rc.local still lost the line. Would you please be kind enough to post your rc.local file so I can see if I am doing something daft. Was there anything else you had to change to get the modified file to stay modified?
Many thanks, Chris

You're right, the RC. LOCAL does not work well. If you do shutodown in the command console is cleared.
The command remains if you turn off the power supply.
So I found another way. You must edit the filebootmisc.sh in / etc / init.d, get to the bottom and after: write a new line like this:
su pi -c "mpdlcd &"
where pi is the user, and the command is in quotes, the debug option is no longer needed.
The only limitation is if you restart MPD, because, of course, the connection between LCDMPD and MPD is broken.
When the raspberry restart everything works again

Hi everyone,
If you have an Adafruit 16x2 Char LCD Plate for your Pi I have written a tutorial how to use it with RaspyFi. It is basically a Python script with the following features:
* Presentation of play mode (playing/paused/stopped), Artist and Song name scrolling on line 1
* The elapsed song time, total song time and percentage of song played on line 2.
* Left button: Skip back
* Right button: Skip forward
* Up button: Play
* Down button: Stop
* Select button: Toggle Play/Pause
You can find the source code and a video of the display in action on: http://didtheypush.blogspot.se.....plate.html

Excellent! Thanks for the info, I might have a go at that at some point when I get some time, maybe over christmas. I notice that us UK folks can get the LCD display + all the tools required from pimoroni (e.g. http://shop.pimoroni.com/produ.....spberry-pi)

The only trouble is that I haven't used a soldering iron in a very long time... and the last time I tried to do something serious with one (maybe 20 years ago?) an electrical engineer took pity on me and re-soldered the mess that I had made. Still, how hard can it be, right?

Cheers,

Karli
